The behaviour of 2-Aryl-1,3-dithiolanes hydrolysis catalysed by perchloric acid have been studied kinetically. The effect of changes in aryl substituent, acid concentration. temperature, and isotopic solvent on the rate of hydrolysis show that the hydrolyses in 6.0 to 9.0 mol dm(-3)) of the acid proceed via A2 mechanism. The results for the dithiolanes seerve to confirm the pattern of behaviour obtained for the dithianes.
